To all whom it may concern;

Be it known that I, THoMAs, C. Loon, a citizen of the United States, residing at Dalton, in the county of Berkshire and State of Massachusetts, have invented a new and useful Cooling 'System for EXPlOSlVQ-EIH gines, of which the following is a speclfication. I

My invention relates to improvements in cooling systems for explosive engines in which a body of water is held between the cylinder and outside jacket and is allowed to circulate through a radiator to. cool, and the objects of my improvements are first; to provide a cooling system for explosion enes that may be allowed to freeze without mage to any part of its mechamsm; sec- 0nd, to provide acooling systemusing water,

that when frozen will melt the ice without damage to any part of the mechanism, by the starting and continued runnmg of the engine; third, to provide a cool ng system for explosion engines with sufliclent radiation on the jacket of the cylinder to eliminate entirely or reduce to a minimum the necessity ofaradiator apart from the acket proper.

I attain these objects by the mechamsm illustrated in the accompanying drawing 1n which-- Figure 1 is a vertical section of the entire cooling system. Fig. 2 is across section of v Fig. 1 on theline 2-2. Fig. 3 is a cross section of Fig. 1 on the line 33. Figs. 1-5 are illustrations of variations in construction of parts of Figs. 1 and 2. v

' Similar'numerals refer to similar parts throughout the several views. I

To the cylinder 3 of an explosion engine is attached a corrugated jacket 5 constructed of some material as of brass or copper, with high conductivity and some tension. The corrugations at the lower end are blended into a round band fitted to the cylinder 3 and held there bythe band 8 which is drawn tight by the-bolt 9. To the explosion chamber 4 of the cylinder 3 the corrugated jacket is attached by being bolted to the face of explosion-chamber 4, under the ring 6.

It will be noticed that the corrugations in the jacket are longitudinal, and this is important; and while the corrugations are not shown as being very deep in the drawing, in practice I make the corrugations deep so as to provide for a very large radlating surface. In this way I attain two important objects. First, I get'a jacket with a very large radiating surface so that the liquid in the jacket is kept cool, and second in case of freezing, the longitudinal corrugations provideamply for expansion so that no injury is done to the jacket.

I am aware that jackets have been used for a certain amount of additional radiating surface, they do not provide for expansion.

poses. Surrounding the vertical sections of the tube 10 are the radiation plates 11 with flanges like those of the rings 12. The tube 10 is constructed oval shape or as shown in cross section in Fig. 5 to allow expansion. Connected with and opening into the water jacket 5 is the tube 15; entering the tube 10 at 17 and lies within the tube '10 to the point 16 where it leaves the tube 10. A heat conducting plug 13 is firmly held in the head of the cylinder 3 and enters into tube 15 and is designed to. conduct heat from the explosions within the cylinder 3 to the opening into tube 15.

Having described these various parts of the cooling system I will further illustrate the action of the same.

By the corrugated construction of the jacket5 as shown in Figs. 2 and 4 and construction of tube 10 as shown in Fig. 5 and by the construction in the form of flanges of the" radiation rings 12 and plates 11 the whole cooling system will expandsufliciently to allow water to freeze Within it without breaking the mechanism and whenthe ice melts the tension of the metal brings it back to its original position.

If the engine is started while the cooling system is frozen the heat from the explosions within the cylinder 3 will be conducted The corrugations of with transverse corrugations, but it will be readily seen that while these might provide-.

along the plug 13 and will melt an Opening into the tube 15 before any steam can be generated within the jacket 5. No water gets into the tube 15 but the heat from the warmed water in the jacket 5 will pass through the tube 15 and gradually thaw an opening of water in pipe 10 along its whole distance to its port at 16. This will establish a circulation and gradually through the radiation plates 11 the heat will be communicated to the other sections of the tube 10. The corrugations of the jacket 5 may be slight as in Fig. 4 or sharp and extended and yet remain within the designs of my invention.

. Having thus fully described my invention 1 I claim 1; In a cooling device for gas engines, the combination of an' engine cylinder, a longitudinally corrugated jacket therefor adapted to retain a circulating liquid, means forming a circulating chamber exterior of said jacket, and means forming a duct connecting with theinterior of the acket extending combination of an engine cylinder, a jacket I therefor adapted to retain a circulating liquid,'means forming the circulating'chamber exterior of said jacket, and means forming a duct connecting with the interior'of the jacket extending above the water level thereof and extending into said circulating chamber.

4. In a cooling device for gas engines, the combination of an engine cylinder, a jacket therefor adapted to retain a circulating liquid, meansforming a circulating chamber exterior of said jacket, a pipe, a plug tapping the said cylinder and extending into said pipe, said pipe extending above the and extending above the liquid level thereof, said plpe passing into the said cooling chamher and having a. vent exterior thereof.

(5. In a cooling'device for gas engines, the combination of an engine cylinder, means forming a cooling chamberexterior of said jacket and communicating therewith near the top and bottom of .the jacket, and a pi'pe connected with the said jacket and extending upwardly and entering the said cooling chamber.

7. In a cooling device, the combination of an engine cylinder, a liquid acket therefor, a circulating pipe forming a cooling chamber exterior of the jacket and communicating therewith near the top and bottom of the jacket, said pipe being substantially crescent shape in cross section and having corrugations in its flattened sides, and means for communicating heat from the engine cylinder to said cooling chamber.

8. In a cooling device the combination of an engine cylinder, a liquid jacket therefor, pipes exterior of said jacket and communicating therewith and leading from one end portion of the jacket to the other, radiation ribs on said pipes. and a pipe communicating with the interior of said jacket extending above the liquid level thereof and entering one of the exterior pipes and having a vent exterior of said pipes.

9. The combination with the engine cylinder and the jacket inclosing the same, of an exterior pipe leading from one end portion of the jacket to the other, said pipe extending outside the said jacket, a second pipe leading from one end portion of the jacket and entering the first named pipe following the course thereof and discharging therefrom, and a heat plug extending from the engine cylinder into said second pipe.
